Overview

Note:

When making an API call, you may pass ScalingConstraints data as a hash:

{
  min_capacity: 1, # required
  max_capacity: 1, # required
}

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activities triggered by automatic scaling rules will not cause an instance group to grow above or below these limits.

Instance Attribute Details

#max_capacityInteger

The upper boundary of EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

Returns:
